SASH-FASTENER.

SPECIFICATION forming part of Letters Patent No. 599,745, dated March 1, 1898.

Application led July 1, 1897.- Serial No. 643,122. (No model.)

To all whom, t maricon/@wm Be it known that I, HENRY L. STEINMEYEE a citizen of the United States, residing at Sacramento, in the county of Sacramento and State of California, have invented certain! new and useful Improvements in Sash-Locks; and I do declare the following to be a full, clear, and exact description of the invention, such as will en able others skilled in the art to which it appertains to make and use the same.

My invention relates to certain new and useful improvements in sash-locks for win`` dows; and the object is to provide a simple, cheap, and effective device of this class; and to this end the invention consists in a sashlock comprising a plate provided with a rectangular slot and integral guide-lugs,` a sliding bolt mounted in said lugs and provided with an integral arm formed with a lockingnotch, a pinion mounted in the path of said bolt, a spring in operative engagement with said arm, and a removable key adapted to engage said notch and lock the bolt out of engagement with said pinion, as will be hereinafter more fully described, and particularly pointed out in the claim. y

In the accompanying drawings the same reference characters indicate the same parts of the invention.

Figure l is a longitudinal section of my improved sash-lock as applied to an ordinary window-sash. Fig. 2 is an enlargedview of the lock detached from the window-frame.

1 represents a rectangular plate provided with a longitudinal casing 2, semicircular in cross-section.

3 represents a pinion transversely jour-p naled in the case 2 and having a portion of end of the sliding bolt, and 8 represents a coil-spring fixed on the stud 9 in the casing, where its free end engages the arm 7 to project the end of the bolt 5 into the path of the teeth on the pinion 3.

10 represents a notch formed on the inner side of the arm 7 andkas shown in Fig. 2, is adapted to engage the end of a detachable key 12 to hold the bolt 5 out of engagement with the pinion when desired.

13 represents a vertical rack fixed to the window-frame in the path of the pinion, with which it is at all times in mesh. When the bolt 5 is inthe position shown in Fig. 2, the window-sash maybe freely raised or lowered at will, and when it is desired to secure the window at any point of its movement the key is withdrawn from the lock, which releases the bolt, Vso that its spring 8 forces it between the teeth of the pinion 3 to lock it, and consequently lock the sash in place, so that it will be impossible to either raise or lower it.

The device is applicable to counterbalance windows or those not provided with weights. In the latter case it acts as a convenient support for the sash independently of its operation as a lock.

'Having thus fully described my invention, what I claim as new, and desire to secure by Letters Patent of the UnitedStates, is-- l A sash-lock comprising the plate 1,provided with a rectangular slot 4, and the integral guide-lugs l6 6, the sliding bolt 5 mounted in said lugs and provided with the integral arm 7, having the locking-notch 10, a pinion mounted in the path of said bolt, the spring 8 inoperative engagement with said arm, and

the removable' key 12, adapted to engage the notch 10 in the arm 7 to lock the bolt out of engagement with said pinion, substantially as shown and described.

In testimony whereof I hereunto affix my signature in presence of two witnesses.

H. L. STEINMEYER.
